| Allegro CL version 10.1 Unrevised from 10.0 to 10.1. 10.0 version |
Arguments: bar-chart-view
Returns the value of the bar-colors property of
a bar-chart-view
. The value
may be set at creation time by passing
the bar-colors
initarg, or any
time later by calling (setf bar-colors).
The colors that are used to fill the interior of the bars of a
bar-chart-view
in a
chart-widget
. The value
should be a sequence (list or vector) of RGB objects
(see make-rgb) and/or symbols
that are globally bound to RGB objects. The default value is a list
returned by the following (the symbols name pre-defined colors, see
make-rgb):
(list 'light-blue 'green 'light-red 'yellow 'cyan 'magenta 'blue 'dark-green 'red 'dark-cyan 'dark-yellow 'gray 'dark-gray)
If the value is nil
, then the bars are not
filled and will be transparent. Otherwise, the first object in the
chart-widget's sequence of chart-objects is drawn with the first color, the
second object with the second color, and so on. If there are fewer
colors in the list than there are chart-objects, then the drawing code
will cycle back through the list of colors as needed.
This property and other bar-chart-view
properties are used only when the
chart-view property of the
chart-widget
is :bar
to display the bar-chart-view
.
